C Correct answer
Explanation
  • The supply of water to the crops at different intervals is called irrigation. Lakes, rivers, dams, canals, etc. are the sources of water for irrigation.
  •  Various traditional ways of irrigation are pulley system, chain pump, dhekli, and Rahat. 
  • Traditional methods are cheaper but they are less efficient as compared to modern methods. The modern methods of irrigation include sprinkler systems, drip systems, etc. 
  • In the sprinkler system, water is sprinkled on the crop by using a pipe and nozzle system. It resembles raining. In the drip system, waterfalls drop by drop just at the position of the root.

Multiple choice physics the essence of change forms of energy and energy conservation energy for everything forms of energy

The flowing water of a river possesses ...... energy.

  1. gravitational

  2. potential

  3. electrical

  4. kinetic
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. This is energy that is used during the execution of processes, such as movement. Because of kinetic energy water can flow and waves can exist.
But water can also contain potential energy. This is energy that is stored in the water. Stored, but not used. This energy can become useful when water starts to flow. It will be transferred to kinetic energy and this will cause movement.
so it is clear that flowing water have kinetic energy .

so best possible answer is option D.

Multiple choice evs - i rules are for everyone need to conserve biodiversity protecting our environment biodiversity loss and need for conservation sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Human activities like deforestation, pollution, global warming etc is  a major threat to the natural resources.The scarcity of water is  a common problem nowadays which needs serious attempts.Rainwater harvesting is the method of conservation of rainwater by reusing the stored water for several domestic purposes. The rainwater is collected from various hard surfaces such as rooftops and or other man-made above ground hard surfaces.

Sustainable water utilization is the vision of the management of natural resources like water and its proper utilization.
Encouragement of natural regeneration of vegetation is also one of the methods to conserve water resource. It will usually encourage species, that are already plentiful in the area and will ensure the vegetation is directly suited to the site. As all of the above are ways to conserve our water resources.

The water holding capacity of Kolleru lake has been reduced due to

  1. Urbanization

  2. Eutrophication

  3. Dam construction

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation


Kolleru lake is the largest freshwater lake in India and is located in Andhra Pradesh. Kolleru is located between the Krishna and Godavari delta. The lake is drying up due to indiscriminate exploitation and urbanization. Kolleru Lake receives a lot of nutrients, leading to eutrophication. The lake’s eutrophication and deterioration in ecological health have occurred steadily and consistently and has thus decreased its water holding capacity. Thus the correct answer is option D.
